Tooltos Ceramic Crucible for Gold Silver Melting | Electric Furnace 1KG 2KG 3KG

Built for Cleaner, More Reliable Precious Metal Melting Graphite crucibles oxidize quickly and introduce carbon into your melt — affecting purity and increasing replacement costs. The Tooltos High Temperature Ceramic Crucible offers a cleaner alternative: oxidation-resistant, dense ceramic construction purpose-built for gold, silver, and copper melting in electric furnaces. Available in 1KG, 2KG, and 3KG capacities to match your batch size and furnace model. Key Features 1000–1100°C Maximum Temperature — Handles gold, silver, and copper melting temperatures without degradation. Oxidation-Resistant Ceramic Body — Produces cleaner melts with no carbon transfer, ideal for precious metal work where purity matters. Double-Ring Opening Design — Provides a stable grip point for crucible tongs during pouring, improving safety and control. High-Density Construction — Consistent performance across repeated heating cycles, reducing replacement frequency. Three Sizes Available — 1KG, 2KG, and 3KG to suit small workshops through small-scale refining operations. Furnace-Ready Replacement — Drop-in replacement for standard electric melting furnaces, including Tooltos models. Best For Jewelry workshops melting gold, silver, or copper Users replacing worn or damaged crucibles in electric melting furnaces Casting studios and repair shops needing reliable daily-use crucibles Users who want cleaner melts with less carbon contamination than graphite Small-scale metal refining with non-ferrous metals Not For Torch or open-flame melting applications — graphite crucibles are better suited for direct flame Iron or steel melting — exceeds the recommended temperature and material range Users who have not confirmed furnace chamber size compatibility before ordering Technical Specifications Specification 1KG 2KG 3KG Top Outer Diameter 66 mm / 2.60 in 74 mm / 2.91 in 74 mm / 2.91 in Top Inner Diameter 36 mm / 1.42 in 44 mm / 1.73 in 50 mm / 1.97 in Bottom Diameter 50 mm / 1.97 in 58 mm / 2.28 in 60 mm / 2.36 in Overall Height 125 mm / 4.92 in 150 mm / 5.91 in 160 mm / 6.30 in Weight 0.30 kg / 0.66 lb 0.40 kg / 0.88 lb 0.40 kg / 0.88 lb Max Temperature 1000–1100°C Material High-Density Ceramic Crucible Type Double-Ring Opening Size Selection Guide Application Recommended Size Small jewelry workshop gold melting 1KG Silver casting preparation 1KG / 2KG Copper alloy melting 2KG / 3KG Small-scale metal refining 3KG Furnace crucible replacement All sizes First Use and Operating Guidelines Inspect — Check the crucible for cracks or chips before first use. Dry — Ensure the crucible is completely dry before heating. Preheat — Gradually increase temperature to avoid thermal shock. Load — Add metal charge without exceeding rated capacity. Melt — Operate within the 1000–1100°C range for best results. Cool — Allow natural cooling only. Never quench with water. Pro Tips Preheat slowly on first use to cure the ceramic body and extend service life. Use proper crucible tongs — the double-ring design provides a secure grip point for safe pouring. Store in a dry location to prevent moisture absorption before use. Inspect after each use — hairline cracks indicate the crucible should be replaced. Dedicate one crucible per metal type to avoid cross-contamination between alloys. Frequently Asked Questions Can I use this crucible for torch melting? This crucible is designed for electric melting furnaces only. For torch applications, graphite crucibles are better suited to handle direct flame. What metals can I melt in this crucible? Gold, silver, copper, brass, bronze, and most non-ferrous metals. Not recommended for iron or steel. How many uses can I expect per crucible? With proper care — gradual heating, no thermal shock, dry storage — ceramic crucibles typically last 20–50 melting cycles depending on temperature and metal type. Is this compatible with Tooltos melting furnaces? Yes. These crucibles are designed to fit standard Tooltos melting furnaces. Please verify the size matches your furnace chamber before ordering. Why ceramic instead of graphite? Ceramic crucibles are more oxidation-resistant and produce cleaner melts with less carbon transfer — ideal for precious metal work where purity matters. How do I choose the right size? Choose 1KG for small gold or silver melting, 2KG for silver casting or copper work, and 3KG for larger copper batches or small-scale refining. When in doubt, refer to your furnace chamber specifications. What's Included 1 × Tooltos High Temperature Ceramic Crucible (selected size) Safety Notes For electric melting furnace use only — not suitable for open flame or torch applications. Always preheat gradually before reaching full operating temperature. Keep dry before heating — moisture causes cracking. Never quench with water after use — allow natural cooling only. Handle with care — ceramic is brittle and will crack from impact. Why Choose Tooltos Tooltos focuses on jewelry tools, workshop machines, and production-ready accessories designed for practical daily use. This ceramic crucible offers reliable high-temperature performance, clear size options for different furnace capacities, and a cleaner melting result compared to graphite — making it a dependable replacement solution for jewelry workshops, casting studios, and small-scale metal processing operations.
